Non-refillable bottle.



RALEIGH ADELBERT BLACK, OF HOBART, TASMANIA, AUSTRALIA.

NON-REFILLABLE BOTTLE.

Specification of Letters Patent.

Patented May '7, 1912.

Application filed July 6, 1910. Serial No. 570,609.

To all whom it may concern Be it known that I, RALEIGH ADELBER'I BLACK,a subject of the King of Great Britain, residing at 107 Collins street,Hobart, Tasmania, Commonwealth of Australia, have invented new anduseful Improvements in Non-Refillable Bottles; and I do hereby declarethe following to be a full, clear, and exact description of the same.

This invention relates to the construction of bottles used to holdspirituous liquors, medicines and other like valuable commodities inliquid form, and has for its object to prevent the bottle beingrefilled.

In carrying the invention into effect I provide a simple and inexpensivedevice, which is placed inside the neck of the bottle and which willconstitute a valve of a peculiar and ingenious kind, as will behereinafter described with reference to the accompanying drawing, inwhich,

Figure 1 is a sectional elevation of a bottle with the hollow plunger inits neck. Fig. 2 is a plan of the top of the plunger, and Fig. 3 asectional elevation of same. Fig. l is a section of the ring forming theseat for the plunger, and Fig. 5 shows the plug for insertion therein.

The neck of the bottle 6 may be formed with its inside surface parallel,and in its base is an annular support 7 upon which the end of the flutedplunger 8 will rest. Member 8 is adapted to an easy fit in the neck andhas a number of more 01' less deep grooves around its periphery theapices of the projections or ribs along the cylinder coming in brushingcontact with the glass surface of the neck. The fluted plunger isinserted in the neck of the bottle after member 7 is placed in positionor is otherwise constituted and is confined therein by the ring 9 orother convenient means, which is placed in position near the mouth ofthe neck. The grooves in the plunger may be parallel or they may bespirally formed longitudinally. The lower end of the plunger iscontracted at 10 and should sit evenly upon the seat provided for it inthe support 7 Instead of using member 7 the base of the neck may beformed with a seat, and the lower end of the plunger ground or otherwiseshaped into a convexity adapted to rest upon the seating in the neck. Ifnecessary, a rubber ring or such like device may be placed upon theconvexity of the plunger for the purpose of improving the seat of thevalve.

The parallel ribs 11 run longitudinally with the neck and the center ofthe plunger is hollow throughout its entire length to receive the plug12 which may exactly fill the hollow space or be only of sufficientlength to fill the space up to the dotted line in Fig. 3. The bore ofthe plunger and the plug are tapered to insure the latter being droppedtherein and secured. The plug may consist of glass, wood or any othersuitable material.

Any suitable means may be employed to retain the plunger in the neck.Thus, instead of the ring 9, the neck near the mouth may be slightlycontracted above the plunger in any known manner and after the latterhas been placed in position.

The depth of the channels between the ribs 11 should be such that freeegress for the liquid contents of the bottle will be possible when theupper end of the plunger is against the ring 9 or other confining means,as will be hereafter explained.

The plunger is inserted without the plug 12 and immediately before theconfining means is placed in position in the neck near the mouth of thebottle. The liquid is then filled through the bore 12 and when thebottle is full the plug is placed in the bore and secured therein in anysuitable manner so as to exactly fill it but preferably only up to thedotted line (Fig. After inserting the plug no more liquid can be filledinto the bottle as the plunger is seating upon the ring 7, but if thebottle is decanted, the plunger, which fits easily in the neck, willleave its seat and move forward till brought up by the ring 9 or otherconfining means. The liquid will thus be free to flow from the bottlealong the grooves between the ribs 11 and out of the mouth past the ring9. A cork may then be inserted in the mouth and the bottle capsuled inthe ordinary way.

It will be apparent that the bore of the neck need not be parallel if itand the plunger are long enough, after allowing for any outward bulgingof the neck, to contact near the top and bottom of the plunger. Thereshould be enough contact between the neck and the plunger near the endsof the latter to keep it upright and to allow for contact as it slidesto and fro.

I claim The combination of a bottle having a neck integral with thebottle, a plunger having longitudinal peripheral ribs thereon slidablein said neck directly against the face thereof, said plunger having atapering axial bore passing entirely therethrough, said ribs hav ingcurved and tapered lower ends, a correspondingly shaped seat secured insaid neck at the lower end of said plunger and adapted to closelycontact a large portion of the curved surface of said lower end of theribs and to close the grooves between said ribs when the plunger isseated, a ring secured in the upper end of the bottle neck for limitingthe upward movement of the plunger, a tapered plug much shorter thansaid bore inserted in said bore, the upper end of the plug terminatingremote from the upper end of the bore, and a cement filling in said boreabove said plug.

In testimony whereof, I have si ned my name to this specification in thepresence of two subscribing witnesses.
